Create empty matrix in python

So, is there a way to achieve the same thing in python as the following line in R: matrix( rep(NA, 3*5), ncol = 5 )

To be more specific, do I need to define an array before reference it in python? How is this process different from MATLAB? I tried to create an array full of 0 using np.zeros((5, 3)), but is there a way to create an empty one and simply keep adding numbers into it?

An array full of 0 using np.zeros((5, 3)) is the best thing you can do here because, there no such thing as "variable declaration" or "variable initialization" in Python.

See this answer: Python variable declaration
